Long coding for ch steering module.

[Newbieintown]

I had the same issue the other week @RetroRaz helped me out big time... I ended up with an abs test mode fault.... driving at 13mph and turning steering wheel between 90-180 was a PITA.... 5am Tesco empty car park did the trick.

Right, got a bit further,

Managed to get the steering to lighten up, still got fault codes in the abs module however, as follows:


                Address 03: ABS Brakes       Labels: 1K0-907-379-MK60-F.lbl
Control Module Part Number: 1K0 907 379 Q    HW: 1K0 907 379 Q
  Component and/or Version: ESP FRONT MK60      0102
           Software Coding: 0004738
            Work Shop Code: WSC 01279 785 00200
3 Faults Found:

01486 - System Function Test Activated
        000 -  -
00778 - Steering Angle Sensor (G85)
        005 - No or Incorrect Basic Setting / Adaptation
01309 - Power Steering Control Module (J500)
        008 - Implausible Signal

The ABS, ESP and TPMS lights are also lit up.

Is it safe to drive as it is?

I think you have the same error code as mine and it needs a dealer reset.
My steering works fine with no dash mil lights.

[MPS]

can't understand why it will of need a dealer reset, been through the swcm swap process several times before and it's always been fine.

01486 - System Function Test Activated
        000 -  -

This is ok, once all other errors are sorted, we can deal with this one by the completing the test. Don't worry about it for now...

00778 - Steering Angle Sensor (G85)
        005 - No or Incorrect Basic Setting / Adaptation

This one is due to steering angle and also steering limit stop basic settings needed. Details on Ross tech for the mk60 abs.
However, I don't think you will be able to clear it while you have the 01309 error.

01309 - Power Steering Control Module (J500)
        008 - Implausible Signal

This will be the cause of your problems.
I would remove and refit and check that all connections are definitely in place.

Also, is the steering module coded in 44 steering assist? If not, this might be cause of your problems.

If your horn doesn't work and steering wheel buttons do not light up, either there is a connection problem or a coding issue.

Other option is to disconnect battery for 20mins and try again .

The ABS, ESP and TPMS lights are also lit up.

It's ok to drive but be aware, your power steering may not function and braking may not be as good, abs may kick in when breaking at traffic lights, junctions etc

Push and hold both your ABS/ESP and TPMS buttons together. Hold them down for about 5 seconds. You should hear a 'bong' sound and the lights will go out.

On steering wheel module coding there are options for the LIN  version as this module supports both v1 and  v2.
If you have the wrong coding, it could cause a communication issue.

[MPS]

If your horn doesn't work and steering wheel buttons do not light up, either there is a connection problem or a coding issue.

Jas

Thanks again for your help

See this is the thing, the horn and the buttons aren't working, but the buttons do light up.

In the past I had loss of button function and loss of horn and it was faulty buttons

[MPS]

In the past I had loss of button function and loss of horn and it was faulty buttons

I wonder if its because I'm trying to use the old type [pre 2005.5] buttons with a newish generation [CH] steering wheel control module?

[jason_rmh]

Before you start worrying about the buttons, lets check a few things.
Ive been out to my car and got a few screen shots for you, a few things to try to narrow this down:

First, goto module 16 - Steering.
Measuring blocks. Check group 6.
This should confirm if there is communication with the module:


Next, check group 4.

Turn the steering wheel while monitoring group 4.
You will probably find that the steering angle DOES NOT change wheel you turn the wheel.
It should, but isnt due to the issue we are trying to solve.

Now goto basic settings in module 44 - Steering Assist.
Check group 7.


Here you should have 'Basic Setting' and 'Init'.
This should say 'OK' and 'Steering Ang Init' which means basic settings are ok and the G85 is initialised.
Yours will most likely say 'NOT OK' and 'Not Init'

Now, I suspect coding may be part of the problem.
Still in module 16 - Steering, check the coding:


Steering module supports old and new communication (LIN) versions.
This is why the CH module is popular as it supports both Mk5 and Mk6 MFSW.

Hover over the coding box and the bubble will appear, giving you the options:


Pay attention to the 5th digit (0xxx?xx: Multi-Function Steering Wheel):
This is where you tell the car which communication the module is to use:

options 1 to 4 = LIN 1.3 (If you are fitting a Mk5 MFSW)
options 5 to 8 = LIN 2.0 (If you are fitting a Mk6 MFSW)

0xxx?xx: Multi-Function Steering Wheel
0 = Multi-Function Steering Wheel not installed
1 or 5 = Multi-Function Steering Wheel w/o Tiptronic and w/o Push-To-Talk (PTT) installed
2 or 6 = Multi-Function Steering Wheel with Tiptronic and no Push-To-Talk (PTT) installed
3 or 7 = Multi-Function Steering Wheel w/o Tiptronic and with Push-To-Talk (PTT) installed
4 or 8 = Multi-Function Steering Wheel with Tiptronic and with Push-To-Talk (PTT) installed

For example, if you are fitting a Mk5 MFSW, with manual gear box ando do not have PTT (voice control), select 1.

My coding is '0000532'.
I have Mk6 MFSW, Manual, Cruise control, button on wiper stalk, No PTT.

So, take a note of your existing coding and check it is correct.
If not update it and see if it sorts out the communication issue.

Report back and we can go from there.

Jas, you're a star, what's your PayPal Addy, have a few pints on me.

Jas, you're a star, what's your PayPal Addy, have a few pints on me.

Has it worked? Was it coding? :)

[MPS]

No haven't tried it yet, just appreciate the lengths you're going to to help a stranger. I'll let you know.

[jason_rmh]

Ok, I was about to 'air punch' then.... I'll save it ;)

Keep us posted.
I had an issue with mine last week so know how frustrating it is trying to decipher what VCDS is trying to tell you.
